A'fWALL CONSTRUCTION yFranky R. Schaaf, Meriden, Conn.

v Applieatian Augnst .29,

3 Claims.

My invention relates to improvements in wall constructions and also to an improved method and an apparatus` for forming or constructing the same.

5 One of the principal objects of my invention is to'provide wall units of a precast construction adapted to be arranged ina manner whereby concrete or the like may be readily associated therewith to form a wall or the like without subsequent removal of said units.

Another object of my invention is to provide va wall construction which is extremely strong and durable and one which may be quickly Aand economically fabricated and within a minimum amount of time.`

Other objects relate more particularly to the provision of an improved method of an apparatus for building such a wall.

Other objects and advantages will be apparent from the following description, appended claims and annexed drawing.

Referring to the drawing wherein like reference characters Adesignatelike parts throughout the several views:

Figure l is aside elevation of a number of my wall units associated together and illustrating one step in the construction of awall or the like. y

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 lis a View similar to Figure 2 illusl trating another step in the construction o f my novel wall. Y. Figure 4 is a longitudinal sectional view illustrating the portion of a ceiling and floor constructed in accordance with my invention.

Figure 5 is a fragmentary perspective view of one of my wall units.

Inasmuch as each of my novel forms of wall 40 units areof a substantial like construction, a description of one will sufce, it being understood that reference characters indicative of parts of one unit are likewise indicative of the same parts of the other units.

My building unit 5 comprises a latticed structure made up. of a plurality of spaced vertically and horizontally extending ribs 6 and 'I respectively, said ribs coacting'together to form therebetween interstices 8. The ribs 6 coact together to form vertically extending channels 6a and likewise the ribs 1 coact together to form horizontally extending channels la. Each of the units 5 are constructed of a mixture of cement and sand and are arranged relative to each 193s,y serial No.` 227,413 (C1. 'z2-48) other to form a skeletonized frame work for a wall or the like.' l l' As illustrated in Figures 1 and 2 of the drawing, the units are set up to form a pair of spaced inner and outer wall frames 9 and II! respectively. The outer face of the frame 9 has secured thereto studs II by means of wires I2. The inner face of the frame 9 has secured thereto a body of insulating material I2 and extending through said materialy I2 and securing theA inner and outer frames 9 and It. together are wires I3. The insulating material I2 coacts with the ribs 6 to form vertically extending dead air spaces within the -channels 6a as, clearly illustrated in Figures 2 and 3 of the drawing.

When the frames are thus set up, concrete or the like is poured betweenthe frame I0 and insulating material I2 and exudes through the interstices of the frame I0 and is floated or troweled over the outer face thereof to form a smooth andneat appearance. Suitable plastic material I5 is applied to the outer face of the frame 9 and floated or troweled thereover. Said plasticl material enters the interstices thereof andfefi'ects anchorage with said frame 9. However, it is to be distinctly understood that the insulating material I2 may not necessarily be used. Thus, when the concrete Illl is poured between the frames said concrete will exude through the interstices of both of the frames and may be iioated over the outer surfaces thereof. It is to be further understood that before the outer surfaces of the frame 9 are dressed, the studs II are removed therefrom. Furthermore,. other plastic materiall may be applied to the outer faces of the frames 9 and Iii and secured thereto by cohesion with the concrete exuded between the interstices. y

With particular reference to Figure 4 a floor and ceiling construction may be quickly arranged lby connecting a pair of horizontally disposedy frames made up of my novel units 5 and connected together by pairs of transversely extending units. For a construction of this character horizontally extending spaced beams are initially provided supported by vertical members. When thus arranged, concrete is poured into and vbetween the vertical extending units and over the uppermost horizontally extending frames and allowed to set.

When the concrete has thus become set, the beams are removed and a plaster or the like may be applied to the lower face of the lowermost horizontally extending frame in the' same materials may be substituted Without departing f from the spirit of the invention or scope oi'- the appended claims.

What I claim is:

1. A new article of manufacture, comprising, a precast integrally fashioned-latticed building unit of plastic material having interstices for receiving other plastic material therein for arichorage to said unit to form an integrant thereof. 2. A new article of manufacture, comprising,

a precast'integrally fashioned building unit havy ing a plurality of connected and angularly related elements of plastic material defining a lattice having interstices for receiving other plasticy material therein for anchorage to' said 'unit to form an integrant thereof.

3. A new article of manufacture, comprising, a precast. integrally fashioned building/unit of a latticed construction having sets of spaced ribs, the ribs of one set being disposed laterally of the other set and extending angularly relative thereto al suicient degree to provide interstices between saidA ribs vfor receiving plastic materialA therein for anhorageto said unit to form an integrant thereof.
